Hi Joel,

I looked into this issue.  The error is coming from the compiler, which is directly forwarded the arguments (with no extra interpretation) from ccc-analyzer.  I'm not certain where the issue is, because I see this problem even when just using the compiler directly (and not using scan-build).  For example:

$ touch t.c
$ cat Makefile 
t.o:
	$(CC) -DFOO=\"Foo Bar\" -c t.c

clean:
	rm -f t.o

all: t.o

$ CC=gcc make
gcc -DFOO=\"Foo Bar\" -c t.c
i686-apple-darwin11-gcc-4.2.1: Bar": No such file or directory
<command-line>: warning: missing terminating " character
make: *** [t.o] Error 1


Note that if I change the relevant line in the Makefile to:

t.o:
        $(CC) -DFOO='"Foo Bar"' -c t.c


the problem goes away.
